[Brienne approaches Joffrey. She bows, somewhat clumsily]
Brienne of Tarth : [to Cersei] Your Grace.
Brienne of Tarth : [to Joffrey] My king.
Brienne of Tarth : [to Margaery] My queen.
[Margaery rises and offers her hand to Brienne]
Margaery Tyrell : Lady Brienne.
[Brienne shakes Margaery's hand]
Margaery Tyrell : So good of you to come.
Brienne of Tarth : [smiles] I'm no lady, your Grace.
Cersei Lannister : [smiles teasingly] Did you just bow?
Brienne of Tarth : [calmly] Apologies, your Grace. I never did master the curtsy.
Joffrey Baratheon : [points at Brienne] You're the one who put a sword through Renly Baratheon.
Margaery Tyrell : That's not true, my love. Brienne had nothing to do with it.
Joffrey Baratheon : [sneers] A shame. I'd knight the man that put an end to that deviant's life.
Brienne of Tarth : I just wanted to congratulate you both and wish you good fortune. The country has been at war too long. I hope your reign is long and peaceful.
Joffrey Baratheon : [bored] Yes, yes.
Margaery Tyrell : [warmly] Thank you. I hope we see more of you.
